CC Eridani is a spectroscopic binary star with an orbital period of 1.56 days that is also a BY Draconis variable star.

Observational history
CC Eridani was first noticed, other than catalog entries, when a parallax measurement determined at Cape Observatory in South Africa showed that it was a relatively nearby star. Due to its status as a nearby star radial velocity measurements were obtained starting in 1951 by David Stanley Evans at Radcliffe Observatory, Pretoria, South Africa. These measurements revealed that it was a spectroscopic binary and photometric measurements were initiated in 1956 to determine if it was variable. The first year of photometric observations indicated a possible eclipsing binary however subsequent years observations did not fit the eclipsing binary model.

Variability
Two x-ray superflares were detected by the Swift Observatory.

Multiple flares were detected by the South Pole Telescope in the millimeter range.
